- This type of flask with a horizontal tube attached to the neck was known as a filter flask, a filtering flask, or a suction flask. The form was in use by the 1890s, for filtering under reduced pressure. It was sometimes associated with Robert Bunsen, the eminent professor of chemistry at the University of Heidelberg.
